TCCS facilitates approvals for driveway modifications and construction; construction impacting storm water easements; demolition and excavation waste; and construction impacting the verge or public open space.

Frequently Asked Questions

What is the traffic warrant system (TWS)?

The TWS is a system developed to objectively prioritise the need for investigations into traffic management issues on residential streets (major and minor collector roads) in the ACT.

How are streets ranked in the TWS?

The TWS takes into account the traffic volume, speed, percentage of heavy vehicles, crash history and land use (presence of shops, schools, etc) on each street. It then allocates point scores against each of these attributes, according to the class of the street. The higher the scores of a street, the
higher the ranking of the street.

How often is the TWS updated?

Roads ACT updates the information in the TWS every three to four years.

The updates ensure that the traffic volume and speed data reflect the results of the most recent surveys. The most recently available five year traffic crash data is also included and the land use generators are reviewed to reflect changes such as shopping centre and/or school closures.

The latest version was released in February 2016.

Why did the ranking of my street change between 2013 and 2016?

The inclusion of new streets in the database (streets in new suburbs as well as streets in old suburbs for which data has been collected) and the updating of data in the TWS database can result in the ranking of some streets to change in either direction. Such changes in the rankings are mainly the
result of changes in traffic volumes and to a lesser extent changes in speed and traffic crashes.

My street was in the 2013 TWS. Why is it not in the 2016 TWS?

The 2013 TWS included data for over 400 residential streets. The collection of up-to-date information for all streets in the TWS has now become a big and lengthy task without making a marked difference to low ranked streets. As such, the 2016 TWS only lists the top 100 streets.

The inclusion of new streets in the database (streets in new suburbs as well as streets in old suburbs for which data has been collected) and the updating of data in the TWS database can also result in the ranking of some streets to change in either direction. Hence, this may have caused your street
to move to a lower ranking outside of the top 100 streets.

In the 2016 update, some major collector roads were also removed from the list as it was considered that traffic calming measures may not be applicable or the best treatment for such roads. Such roads will be investigated, and treated if necessary, under other Roads ACT programs.

My street is not ranked. When will it be investigated?

All complaints about traffic conditions on residential streets are investigated, and traffic data collected if unavailable and deemed necessary. The street is then added to the TWS database and ranked accordingly. The 2016 TWS, however, only lists the top 100 streets in the database. Streets that rank
higher on the TWS receive priority in terms of investigations.
